Imagine you’re on the beach. It’s a hot day (like today🥵)
You’re wearing a polyester jacket, sweating and getting hotter by the minute. Now swap it for a linen shirt, it can breathe and you can stay cool in the breeze.
That’s how Antoinette from Agreka Build described the difference between synthetic and biobased isulation at Futurebuild last week. What a great analogy!
I was at Excel London for the day, crossing the concourse between Futurebuild and Accountex because I was genuinely interested in both shows.
The panel on biobased and natural building materials was hosted brilliantly by Ele George of Ele-vate, and the speakers brought it to life in the best way.
John Ferguson from Sisalwool talked about sisal insulation finished with wood wall and lime plaster. Antoinette from Agreka Build is taking agricultural waste and turning it into Wheatex. Chris Brookman from Back to Earth is championing woodfibre with Agrement certification behind it.
The message underneath all of it was that biobased materials need to move into mainstream construction. Not as a niche or a premium option for eco-conscious self-builders, but as standard.
I’m a bookkeeper, not a builder. But my clients are in this space and the more I understand what they’re working with, why it matters and what’s coming, the better I can support them.
